You can grow a wide range of fruit and vegies here in CNX, but you must consider the Fruit Fly, they can destroy a crop of tomatoes, mangoes and the like almost overnight.
Also, things like pumpkins, melons and the like are best grown with their fruit suspended of the ground.
I think a good investment for the home gardener is an insect proof shade house - and there's no need for chemical sprays.
In addition to what drtreelove above has said there are many shops in CNX (i.e., Rimping, HomePro, Big C etc) that also usually have a range of seedlings and seeds for sale.
In our little plot we have around 20 different fruit trees growing and about the same in herbs and vegies. Good luck and enjoy
